fbsql_data_seek

Opis

bool fbsql_data_seek ( resource result_identifier, int row_number )

Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki.

fbsql_data_seek() moves the internal row pointer of the FrontBase result associated with the specified result identifier to point to the specified row number. The next call to fbsql_fetch_row() would return that row.
